' of which the following is a specification.

Myi nv'ention has for its object the automatic stopping of the support of the record of a taiking machine when the end of a record is reached, whereby such stopping will'be instantly and positively effected, and the defacing of the record and the production of objectionable sounds will be prevented. V

The invention consists of novel means for adjusting the device relatively to the extent of movement of the reproducer supporting arm of the machine, whereby the brake of thed'evice will operate with promptness and precision'on the record support.

It'consis'ts also of novel means for moving the brake-operating member of the device.

It consists also of novel details of construction. J

The invention is satisfactorily illustrated in the accompanyi ng drawing, but the important ihstrumentalitiesthereof may be varied, and so it is to be understood that the invention i's not limited to the specific details shown and described.

Figure l-represents a top or plan 'view of ai -automatic stopping attachment to sound producing and speaking machines embody- 'ing my invention. zelevation thereof on an enlarged scale. 1* 1g.

Fig. 2 represents a side s'frepresents a longitudinal vertical section thereof. Fig. i represents a horizontal section of a portion on line ma2 Fig. 2. Fig. 5 represents a transverse vertical section on line y-y Fig. 3.

Similar numerals of reference indicate corresponding parts inthe figures.

"Referring to the drajwings :l designates a box or casing on a--side of which 15 a chamber 2 within which is the brake shoe 3, th'e'latt'er being mounted eccentrically by the ve'rti'cally'extending pin 4: on the upper wall of's'aid opening and base 5 of the casing,

the periphery of the record-support or turn table, say as in Fig. 1.

On the casing are mounted the heads and 8 which are adapted to slide thereon n the direction of the length thereof, said heads being separable from each other. Depending from and secured to the head 7 is the tongue 9 which freely occupies the longitudinally-extending passage or opening 10 in the casing 1, so as to be movable in said passage while it is movable with said head 7. The head 8 rests on said tongue 9 and is connected therewith by a friction joint which is composed of the spring or spring plate 11 which bears against the underside of the upper wall 12 of said tongue and is connected with the head 8 by the screws 13 which pass through said spring and freely.

occupy and are adapted to ride in the longitudinally extending passage or channel 14; in said wall 12, and from whence they enter said head and so are secured thereto, whereby when superior force is applied to the head 8, it may be moved on the tongue sliding thereon, thus adapting the said head to be adjusted to and from the head 7,-but under ordinary circumstances the friction joint couples said head 8 with said tongue whereby said tongue and head may move as one.

Rising from the head 7 is the pin or post 15, and rising from the head 8 is the pin or post 16. The front end of the tongue 9 is cut away forming the incline or slope casing.

said tongue in the casing, and consequently of the heads 7 The operation is as follows:The head 8 is separated from the-head 7 relatively to the adjustment required for the throw of the arm 19 of the machine. Then the side .of

. out the shoe and pressing it firmly against the record support, this being at the instant of the end of the throw of said arm when the record has completed its work, and so positively stopping said support that the needle or the sound producing device 20 is prevented from scratching or marring the record, or causing objectionablesounds by said device. The arm may then be moved to the right, whereby its side will contact with the post 15 and so restore the head 15 to its normal position, and with it the head 8, and

the tongue 9, without disturbing the ad vjustment of the head 8, the brake shoe being released of the tongue and free to move into the chamber 2 and so clear of the record,- support. When a new record is applied, the arm is again placed against the post 16 and the machine started when the operation of the attachment repeats.

Having thus described my invention what I claim as new and desire-tosecure by Letters Patent, is

1. In a stopping device of the character stated for a talking machine, a brake shoe, a

plurality of movable heads, having means between which the tone arm is received, and a member on said heads for operating said shoe, one of said'heads being adjustably mounted on said member, and adapted to move with it said member and the other head as one.

In a stopping device of the character stated for a talking machine, a casing, a brake shoe, a support having means between which the tone arm is received therefor, a plurality of heads'on said support, a memher on said support adapted to operatively engage said shoe, the same being attached to one of said heads, and to be frictionally connected with the other head, adapting the last named head to be adjusted relatively to a movablemember of said machine.

3. In a stopping device of the character stated for a talking machine, a brake shoe thereon, a slidable member in said casing adapted to engage said shoe, and a plurality .of heads on said casing having means be- .tween which the tone arm is receiyed, 011% head being fixed to said member, and the and from the top of said other head being movably connected with the same adapting the latter named head to be adjusted relatively to a movable member of the machine which is adapted to engage said adjustable head.

In a stopping device of the character stated for a talking machine, a casing, a plurality of heads thereon adjustably separated and having means between which the tone arm is received, a tongue attachedto one of said heads and adjustably connected with the other head by a friction joint, and a brake shoe on said casing adapted to be engaged by said tongue and forced out by the same, said last named head being adapted to beengaged by a 'movable member of said machine.

5. In a stopping device of'the character stated for a talking machine, a casing, a movable tongue therein, a brake shoe on said casing adapted to be engaged by said tongue, a head onsaid casing attached to said tongue, an auxiliary head on said head, a friction joint connecting said auxiliary head with said tongue, and means on said auxiliary head for the engagement of a movable member of said machine therewith.
